GCC 4.6, LLVM/Clang 2.9, DragonEgg Five-System Benchmarks

GCC squeezed by to be slightly faster than DragonEgg with the 7-Zip compression test. The Clang 2.9 front-end could not successfully build 7-Zip, but LLVM developers have reported success on their end building the upstream version.

For FLAC audio encoding, the DragonEgg/Clang-produced binaries were faintly slower than GCC on the Intel systems and the slowdown was more evident on the Fusion and Opteron AMD systems where LLVM suffered even more. GCC 4.6.0 does seem to be slightly faster in this test than GCC 4.5.2.
